STRUCT PSI_WRITE_ARGS(9)

💖 NAME 💖

okay bestie, welcome to struct psi_write_args(9) from the Kernel API Manual 🫶 — this struct is literally the arguments for the PSI packetizer. That's the whole name, and it's iconic ✨

✨ SYNOPSIS ✨

Here's the exact shape, no cap — keep it character for character if you're typing it out 💅

struct psi_write_args {
    void *dest_buf;
    void *from;
    size_t len;
    u32 dest_offset;
    u16 pid;
    bool new_psi_section;
    u8 *continuity_counter;
    bool is_crc;
    u32 dest_buf_sz;
    u32 *crc;
 };

🧚 Members 🧚

Every member, served fresh, no skips 🍓

• dest_buf — the buffer to write into ✍️
• from — the PSI data to be copied 🌀
• len — how much to write, periodt.
• dest_offset — where to start writing in the dest_buffer 👀
• pid — the TS packet ID 🎫
• new_psi_section — set when starting a table section 👑
• continuity_counter — incremented on every new packet 🔁
• is_crc — set when writing the CRC at the end 🧾
• dest_buf_sz — the size of the dest_buffer 📏
• crc — a pointer to store the crc for this chunk 🫶
